OCZ Releases Second Generation of Proprietary Virtualized Controller Architecture


OCZ Technology today released of the second generation of its proprietary Virtualized Controller Architecture (VCA), which supports a rich enterprise feature-set enabling flexibility, increased performance, and the reliability required for high throughput storage systems.

"OCZ's proprietary VCA technology is the next step in the evolution of virtualization layers for solid state storage. VCA 2.0 enables industry-leading configurable performance aggregation along with a rich enterprise feature set not found on competitive products," said Ryan Petersen, CEO of OCZ Technology Group. "With its scalable performance, TRIM and SCSI unmap support, and enhanced management tools, VCA 2.0 provides superior reliability and superior performance, in a plethora of OCZ's easy-to-deploy storage solutions."

Building on the company?s first generation VCA technology, which was originally deployed in OCZ's Z-Drive R3 PCIe and Talos SAS SSDs, VCA 2.0 provides even greater enterprise flash management features. In OCZ's enterprise PCIe devices, VCA 2.0 supports the creation of a virtual pool of logical units (LUNs) and features configurable performance aggregation, simplifying data management without impacting performance. VCA 2.0 is the only virtualization layer in the industry with TRIM and SCSI unmap support, which enhances the sustained performance by significantly reducing the overhead associated with garbage collection.

Additionally, VCA 2.0's user-selectable data recovery and non-stop modes allow for data protection, while consolidated SMART support provides system administrators with features for monitoring, analyzing, and reporting device attributes. VCA 2.0 also supports complete power fail protection. In the event of unexpected system power loss, OCZ?s enterprise power fail protection completes all in-progress transactions, protecting the integrity of all active data.

When combined with OCZ's SuperScale storage controller, VCA 2.0 provides benefits to users by allowing certain direct memory access (DMA) and data management functions, including OCZ's command queuing and queue balance algorithms, to be handled by the onboard processing core. This results in higher performance and reduces the burden on the host CPU.

VCA 2.0 technology will become available with the launch of OCZ?s upcoming workstation and enterprise-class PCIe SSDs, including the RevoDrive 3 and Z-Drive R4.
